Seems to suggest changing selector forks as one area but that appears to pretty much mean full gearbox rebuild

Looks like gearbox oil cooler is needed as a minimum. Unsure which one to get Komotec or H111 both seem to locate the cooler in different areas of the car. Anyone got any recommendations on which is better?

Hoffmans also do a cooler too - different to the Komo-tec one. Trouble is, because we don't have a gearbox temp sensor we have no idea if the box was getting too hot, or how effective the cooler actually is.

If you already have SSC gear cables you could go for innovate mounts to reduce engine and gearbox movement and for synchros use redline mt90 (or maybe even mtl if used only on street at lower temperatures)

I have the 380 open gear linkage but if yohave to older shifter there are a few things to make it better that you can do on the exige s2 that could maybe be the same on the v6 but for that you would have to search the forums.

Oil cooler is also a good thing

Purge your clutch master cylinder and make sure your clutch is still ok

Other than that your synchros or other gearbox parts could be worn out and need replacement

Some Lotus tuner suggested to use some racing brake and clutch fluid as Castrol srf as the fluid tank should be the same for both and when the brakes heat up the fluid on track it could also meke the clutch fluid overheat
